How can we remove SkiaSharp and instead use native WPF drawing?

Can I get some feedback? what is wrong with SkiaSharp?

It looked at the binary directory so I could see what I need to add to my WIX installer and noticed the top 5 dlls and dylib (whatever those are) are a total are: libSkiaSharp.dylib (15 MBs), libSkiaSharp.dll (7 MBs), libHarfBuzzSharp.dylib (2 MBs), libHarfBuzzSharp.dll (< 1 MB) and SkiaSharp.dll (< 1 MB) for a total of about 26 MBs. I provide my customers with both exe and msi installers so that adds 52 MBs to my upload not to mention there are a few other dlls like HarfBuzzSharp.dll, LiveChartsCore.SkiaSharpView.dll, LiveChartsCore.SkiaSharpView.WPF.dll, LiveChartsCore.SkiaSharpView.WPF.xml, SkiaSharp.Views.Desktop.Common.dll, SkiaSharp.Views.WPF.dll and SkiaSharp.HarfBuzz.dll which it appears all need to be shipped. That's a lot of dlls which are just all wrappers around Windows GDI (or possibly another API???).

I also just noticed in my x64 directory another 10 MBs of files :(. libSkiaSharp.dll and libHarfBuzzSharp.dll.

This is a good point; I will explore the SkiaSharp repo to find if there is something we can do here.

On the other hands using SkiaSharp has also a lot of benefits (from the library perspective), the library can now run in the browser, mobile, Linux and MacOS.

Also, in theory we could consume the core of the library and draw everything using something else, but even the code is designed for that, there are a few things that needs to be cleaned, maybe in a future this will be possible.

It seems the skia is adding files to the binary directory not needed. Specifically the dylib appear to be Mac libraries. I deleted them and the sample worked.

When comparing memory footprints, the sample app is taking 100 MBs of memory with the basic pie loaded. My app, which is massive, consumes ~75 MBs of memory loading a PieChart using LiveCharts 1. So it seems the skia libraries are consuming way more memory then necessary. This is a really bummer. I want to move forward with the new version because the ChartUpdater is no longer used which should significantly improve performance IMO however the memory footprint is just too much.

There is a huge difference in performance in v2, take a look at this article that explains more about the future performance of the library:

https://github.com/beto-rodriguez/LiveCharts2/releases/tag/v2.0.0-beta.350

There are multiple improvements in v2, about the memory used, I will take a look on that, beta-700 version improved memory allocation.
